What is an aneurysm?
An aneurysm refers to a bulge or enlargement in a section of an artery that’s most often caused by weakness in the arterial wall and can occur in the brain, heart or intestines. Most aneurysms do not rupture. There are often no noticeable symptoms of an aneurysm but if it ruptures, it could lead to internal bleeding – a stroke – which can be fatal. Warning signs that may indicate an aneurysm has ruptured include a sudden, severe headache, blurred vision, droopy facial features (usually on one side), seizure, loss of consciousness and nausea.
